Does JPG to PDF Resize My Images?
JPG to PDF doesn't resize, crop, or stretch your images to fit a standard page. Each page is created at exactly the pixel dimensions of the image it came from — a 4000×3000 pixel photo produces a page sized to those exact proportions.
This means the resulting PDF's pages won't be a consistent size if you combine images with different dimensions or aspect ratios, since each page is sized independently. A PDF made from a portrait photo and a landscape photo will have one tall page and one wide page, not two uniform ones.
This trade-off keeps your original image quality and framing completely intact — nothing is cropped or distorted to fit a fixed page size. If you need uniform page sizes, it's worth resizing or cropping your images to matching dimensions before converting.
